Thrax

[JordanCirk]

I'm wanting to have a hybrid version of my {Sidisi, Brood Tyrant} deck, meaning I want to swap out most of my Sidisi deck back and forth between her and {Thraximundar}. Which cards work well within Thrax, or what are some grixis/rakdos/Izzet goodies for a zombie tribal deck? All help is greatly appreciated.
